As far as I know the "CR-ROM port" on the Sound Blaster is just a non-standard
SCSI conector. So what you need is a SCSI cable to connect your CR-ROM to a
SCSI controler (which you also need one of). Then you can try assuming that
the SCSI CD-ROM you have acts like most others and just try the pre-existing
driver that comes with Julian Elischer's SCSI driver (assuming you have
one of the supported controlers, which as far as I know the Sound Blaster is
_not_).

It is (anticipated that more SCSI controllers will be supported).
Hunt through the last week or so of news and find the new SCSI drivers and
look them over. I don't know what SCSI controler is best for you, if all you
want is the CD-ROM then even the slowest SCSI controler should be much faster
then the drive, just get the least expensiave one that is supported, or has
the docs you need. If you want to put a disk drive, or tape backup on someday
you should start looking at the speed...
